3. Potting
Make certain the potting compound completely surrounds heat sources and maintains full contact with cooling surfaces.
4. Curing
Carry out curing at ambient temperature or elevated temperature according to process requirements.
Packaging & Storage for silicone potting compound:
Standard Packaging: 25kg per drum for both Part A and Part B.
Storage: Keep in cool and dry conditions.
Shelf Life: 6 months for unopened original packaging.
FAQ for silicone potting compound:
Q: What level is 0.76 W/m·K?
A: It is a medium-high level for potting compounds, suitable for most power electronics, effectively reducing hot-spot temperatures.
Q: Are thermal conductivity and electrical insulation contradictory?
A: No, this product is designed for electronics, balancing both thermal and electrical performance.
